They already started making mistakes with the 8700
I have an 8290. It's a real bb. Maybe the last real model. Full qwerty kb, very convenient holster, long battery life, quick recharge times. The lousy parts are the screen (old generation, low dpi, bad colors), slow gprs, awkard internet navigation. Thank god for bblight, at least auto screen light is not longer an issue.
Enter the 8700. Yes it has a new generation screen and better internet browser. Oh and poliphonic ringer, c'mon, we're business users here not teenagers. And now the problems. Holster sucks big time, it's closed type with magnetic lock. No more "draw it like a gun with one move". Screen goes completely off when you don't use it (I hate that, I have to see a any time what happens). Battery is a tad smaller. Keyboard is not so comfortable.
And the down slope has begun.
